Hello Thomas,

and you have written GUI in FP style? with trees, d&d support and so on?
I haven't, I'm working on a different part of the app √ Peter Verswyvelen has though.
:) the problem is that no GUI library except for gtk2hs supports d&d. and i think that no functional GUI library support trees too
it's why i asked - you work on functional part of project and FP features are enough for your work. and you think that everything that you personally don't use should be omitted from haskell
To get back on topic though... Here's *why* I don't want these specific things I wouldn't use added to haskell: • The syntax gains very little over the nice consistent syntax we already have – all you do is move a symbol a little to the left. • For that small benefit we gain all these disadvantages • The language gets harder to parse • We gain more reserved words that we can't use in our programs • We gain more corner cases that can't be explained simply using the basic rules of how application works in Haskell • We gain a syntax that even more than previously indicates that things will be executed in order (which is a total lie) • We encourage people to write code unnecessarily in an imperative style Hope that helps clarify why I'm objecting to this.
